Video

Yesterday, I posted a blog entry on my TimeLapser application, and how it was used to document the working process of the making of the sculpture Hommage til kaffeselskapene by my mother. The final timelapse video looks like this: Now I have run this timelapse video through my VideoAnalysis application, to see what types of analysis material can come out of such a video. The average image displays a “summary” of the entire video recording, somehow similar to an “open shutter” in traditional photography....

I have recently started moving my development efforts over to GitHub, to keep everything in one place. Now I have also uploaded a small application I developed for a project by my mother, Norwegian sculptor Grete Refsum. She wanted to create a timelapse video of her making a new sculpture, “Hommage til kaffeselskapene”, for her installation piece Tante Vivi, fange nr. 24 127 Ravensbrück. There are lots of timelapse software available, but none of them that fitted my needs....

Yesterday, Ståle presented a paper on mocap filtering at the NIME conference in Daejeon. Today I presented a demo on using Kinect images as input to my sonomotiongram technique. Title Kinectofon: Performing with shapes in planes Links Paper (PDF) Poster (PDF) Software Videos (coming soon) Abstract The paper presents the Kinectofon, an instrument for creating sounds through free-hand interaction in a 3D space. The instrument is based on the RGB and depth image streams retrieved from a Microsoft Kinect sensor device....

Earlier this year, before I started as head of department, I was working on a non-realtime implementation of my sonomotiongram technique (a sonomotiongram is a sonic display of motion from a video recording, created by sonifying a motiongram). Now I finally found some time to wrap it up and make it available as an OSX application called ImageSonifyer. The Max patch is also available, for those that want to look at what is going on....

I am currently working on a paper describing some further exploration of the sonifyer technique and module that I have previously published on. The new thing is that I am now using the inputs from a Kinect device as the source material for the sonification, which opens up for using also the depth in the image as an element in the process. To be able to create figures for the paper, I needed to record the input from a Kinect to a regular video file....

Today the MIT Press journal Leonardo has published my paper entitled “Some video abstraction techniques for displaying body movement in analysis and performance”. The paper is a summary of my work on different types of visualisation techniques of music-related body motion. Most of these techniques were developed during my PhD, but have been refined over the course of my post-doc fellowship. The paper is available from the Leonardo web page (or MUSE), and will also be posted in the digital archive at UiO after the 6 month embargo period....

I am happy to announce that a paper I wrote together with Victoria Johnson has just been published in Computer Music Journal. The paper is based on the experiences that Victoria and I gained while working on the piece Transformation for electric violin and live electronics (see video of the piece below). Citation A. R. Jensenius and V. Johnson. Performing the electric violin in a sonic space. Computer Music Journal, 36(4):28–39, 2012....

The last of the four Sverm videos by Lavasir Nordrum hast just been posted on Vimeo. The first short movie was titled Micromovements, then followed Microsounds and Excitation, and the last one is called Resonance. It has been exciting to work with the video medium in addition to the performances, and it has given a very different perspective on the project.

Video artist Lavasir Nordrum hast just posted the third of four short movies created together with the Sverm group. The first short movie was titled Micromovements, and the second was titled Microsounds. This month’s short movie is called Excitation, and is focused on the first half of an even or action. This will be followed by a short movie called Resonance to be released on 1 January.

As I wrote about last month, the Sverm group has teamed up with video artist Lavasir Nordrum. The plan is that he will create four short and poetic videos documenting four of the main topics we have been working on in the Sverm project. The production plan for the videos is quite tight: we shoot content for the videos during a few hours in the middle of each month, and then Lavasir publishes the final video two weeks later....
